Specification of Letters Patent. 3t ,19, 1920,

Application filed September 13. 1 919. "Serial No. 323,488. I

To all whom it may concern Be it known that I, LEROY E. KNIGHT, a

citizen of the United States of America, re

siding at Bethlehem, in the county of Northampton, and State of Pennsylvania, have in vented new and useful Improvements in Curtain-Poles, of which the following is a specification.

This inventionrelates to curtain poles for the support of curtainsor other draperies,

and has for its object the provision ofa. curtain pole formed in longitudinally ad j ustable sections having engaged upon their outer ends block members adapted for engagement with the confronting faces of a door or window frame, the longitudinal relative movementof the sections permitting the pole to be extended and jammedwithin a door or window frame whereby the pole will be adequately supported merely by friction without the necessity for employing screws,

7 nails, or other securing members, the block" members having their faces covered with felt or other suitable material wherebyto prevent injury to'the finish of the woodwork.

An important object is the provision of a Another object is the provision of a tele scopically adjustable pole of this character in which the construction is such that the after more fully described and claimed, and

illustrated in the accompanying drawings in which- Figure 1 is a view of a door frame showing my pole in position therein and supporting drapery,

Fig. 2 is a longitudinal sectional view tary through a. pole construction in accordance metal, j

Fig.3 1s a cross sectional view,

with my invention and made entirely of Fig- 4 is a, side elevation, showing i pole formed partly ofwood and partly of metal,-' j- 5'is a longitudinal sectional view,

Fig. 6 is a cross sectional view. 'Fig. 7 is an enlarged :detail view of one end of the pole shown in Fig. 2, and i Fig. 8 is an enlargedxdetail view of one end of the pole shown jinFig; 5.

'Referring more particularly to. the drawings, the-letter A designates a" door frame,

B designates my pole as a whole, and C designates drapery supported thereon.

Incarrymg out my invention Imay fornr the pole entirely of metal, as in Fig. 2, or partly of metal. and partly of. wood, as shown in Fig. 4. j

Referring especially toFig. 2, it will be seen that my pole comprises'sections 10 and 11 which" are telescopicallyengaged. The

section 10 has secured therein intermediate its'ends a nut" member :12 having a bore within which is engagedathreadedrod '13 extending longitudinally of the pole and carrying at the other endthereof a knurled or milled operating head 14;. The rod 13 projects beyond the end of the section 11,

as shown, and is engaged within a recess 15 formed in a block member 16 formed preferably of wood. This block member is inclosed within a metallic shell 17 and has a flat face covered with felt 18 adapted for engagement with one side of a door or window frame. At its outer end, the section 10 is engaged upon a reduced. extension 19 formed upon a block 20 similar to the block 16. The head 14 is formed on opposite sides with grooved collars 14 with which are engaged flanges 11 and 17 formed on the ends of the sections 10 and the shell 17, respectively; I

In the use of'this form of the device it willbe seen that the pole is disposed within a door or window frame and the head let rotated to eifect'rotation of the rod 13. R0-

movement of the rod. in the proper direction will cause relative longitudinal movement of the sections 10 and 11 which Will result in longitudinal expansion of the pole to bring the flat felt covered faces of the blocks 16 and 20 into firm frictional engagement with the door or window frame whereby to hold the pole securely in position. flanges within the grooved collar of the operating head, the rod will always be concealed and the pole will have a substantially smooth and neat appearance.

In Figs. at, 5 and 6 I have shown the major portion of the pole 21 as formed of wood and this pole is provided in one end with a recess 22 within which is secured a nut member 23. One end of the pole 21 is received within a tubular extension 24: formed on a shell 25 surrounding a block 26 having a fiat face covered with felt 27.

At its other end the pole 21 is slidably received within a tubular member 28. A rod 29 is disposed within this end of the pole and is threadedly engaged within the nut member 23 and this rod 29 carries: an operating head 80. The end of the rod projects beyond the head 80, and is received within a socket 81 formed in a block 32 inclosed within a shell 82 having a felt covered flat face 33, the construction of this block member being identically the same as that of the block member 16. The head 30 is provided on opposite sides with grooved Owing to the engagement of the" From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very simple and inexpensive pole which is so formed that it may be expanded so that the end members carried thereby may be frictionally engaged within a door or window opening whereby the pole will be adequately supported so as to sustain the weight of any draperies disposed thereon.

VVhile I have shown and described. the

preferred embodiments of my invention, it

is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not'depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim V V A curtain pole comprising a pair of telescopically engaged sections, a jam engaging block member carried at the end of one sec' tion, the other section being provided at its end with an inturned annular flange, a nut member secured within said first named section, a threaded rod extending through both of said sections and'engaging within said nut, anoperating head at the outer end of the second named section secured to sald
